Supplier's note

  1. Three Technical Breakthroughs:

    • Enhanced Cooling System: Hyper-cooling fins in the Pro Model reduce operating temperatures by 30% compared to industry standards, enabling use in extreme environments.
    • Material Innovation: The Advanced Model’s stainless steel components boost corrosion resistance by 40%, ideal for marine or chemical-exposed applications.
    • Modular Mounting Design: Customizable flange dimensions allow seamless integration into non-standard Cummins engine setups.

  2. Optimal Version Selection:

    • Base Model: Suitable for standard diesel engines requiring baseline power (e.g., light commercial vehicles).
    • Advanced Model: Recommended for heavy-duty machinery (e.g., construction equipment) needing higher output and corrosion resistance.
    • Pro Model: Best for extreme applications like mining or offshore machinery, where uninterrupted performance and extended durability are critical.

With the Pro Model’s hyper-cooling system, you can sustain peak power output in temperatures exceeding 60°C. Pair this with its 12-month warranty to minimize downtime in high-stakes operations. The Advanced Model’s corrosion-resistant material ensures longevity in saltwater or industrial atmospheres. Choose wisely based on your engine’s power demands and environmental conditions.
